PIPE ROOF-FLASHING.

Specification of Letters Patent.

Patent-ed. Mar. 23, 1920.

Application filed January 17, 1919. Serial No. 271,638.

2"!) cZZ "whom it may concern:

Be it known that EDWARD McCartney, a citizen of the United States of America, residing at Spokane, in the county of Spokane and State of lVashington, has invented ne Y and useful Improvements in Pipe Roofl lashings, of which the following is a specification.

This invention pertains to pipe roof flashings and has for its object to provide a con struction for Bushings that will make a per- Jnanent water-proof connection between the flashing and the pipe. In brief, the invention consists of a malleable upward extension to the flashing, with an outer surface on an angle, or curved and angular, a ring or ban d driven to a tight fit over the extension after the same has been placed over the pipe, then calking around the pipe and around and over the ring or band. The de tails of construction will be hereinafter described and illustrated in the accon'lpanying drawings in which, 7

Figure 1, is a side elevation of a broken away portion of a pipe with the improved flashing secured thereto in connection with which a band is used.

Fig. 2, is a combined elevation and vertical sectional view of the same, showing the band calked in on one side and uncalked on the other side.

F 3, is a combined. elevation and vertical sectional view of a broken-away portion of a pipe and of the flashing in connection with which a ring is used.

Fig. 4., is an end view of one form of a l'llttllfiitlllle extension.

5, is a side elevation of the same.

Fig. 6, is an end view of aband used in the construction.

Fig. 7, is a side elevation of the same.

F 8, is an end view of a ring used in the .:onstruction.

Fig. 9, is a side elevation of the same, and

F5. 10, is a combined side elevation and. versical sectional view of one form of flash ing extension used in the construction.

In a detail description in. which like numerals refer to like parts throughout the sev:

eral views, to the top of the ordinary roof flashing 11 is secured as by soldering at 12 ainalleable upward extension 13, the same having an angular surface as shown in Figs. 1, 2, and 10, or a combined angular and curved surface as shown in Figs. 3, 1 and 5.

The flashing 11 with the extension 13 at tached is placed over the pipe 1d and a band 15 or ring 16 pressed down tightly over the extension 13 and then the upper end. 13 of the extension 13 is manuallycalked against the pipe let and against and over the band 15 or ring 16, as shown in Figs. 1, 2 and 3. In Fig. 2 where the band.15 is used one side of the sectional portion shows the band 15 calked down as at 17, while the other side shows the band 15 before the same is calked down, as at 18.

The exact form of the surface of the ex tension 13 is not essential providing the same is such that the farther down the band 15 or ring 16 is pressed the tighter the same will be. The form shown in Figs. 3, 1 and 5 may be used, or perhaps a better form is the one shown in Figs. 1, 2 and 10, the same being a direct inner angle.

The angular portion 11 and the roof portion 19 are of ordinary construction.

It is understood that the band 15, or ring 16, are flexible to the extent that they will conform to the outer surface of the pipe whether the same be round or otherwise, regular or otherwise, and that the calking will fill tightly the space between the pipe and the malleable extension, including sand holes, seams, etc.

What is claimed is:

1. A pipe roof flashing comprising a roof portion, an. upwardly and inwardly extend ing hollow portion, an upwardly extending malleable portion secured to the upper end of said upwardly and inwardly extending portion and a flexible ring or band externally and tightly engaging the outer surface of said malleable extension.

9.. A pipe roof flashing comprising a roof portion, an upwardly and inwardly extending hollow portion, an upwardly extending malleable portion secured. to the upper end of said upwardly and inwardly extending portion, and a flexible ring or band externally and tightly engaging the outer surface of said malleable extension, and a lock for the band or ring in said position.

- In testimony whereof I affix my signature in presence of two witnesses.
